TRUMAN (INARAMORE, OF WILLISTON, VERMONT.

RAILROADR AIL AND TIE ELEVATOR AND LlFTlNG-JACK.

SPECIFICATION forming part of Letters Patent No. 276,452, dated April24, 1883.

Application filed October 6, 1882. (No model.)

To all whom it may concern:

Be it known that I, TRUMAN G. NARAMORE, acitizen of theUnited States ofAmerica, residing at Williston, in the county of (Jhittenden and Stateof Vermont, have invented certain new and useful Improvements inRailroad Tie and Rail Elevators and Lifting-Jacks; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being bad to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of specification.

My invention relates to improvements in devices i'or raising andsustaining heavy bodies.

It consists of a gearwheel, to which a pinion is so attached that itsteeth shall mesh directly with those of a rack-bar, so that by therevolution of the gear-wheel by means of a lever-socket pinion therack-bar is moved vertically at the will of the operator. The entiremechanism is composed of few and simple parts so directly combined as toconcentrate the greatest power in the cheapest and most durable manner.

Figures 1 and 2 are side elevations taken from opposite sides.

A represents a gear-wheel, to which is attached the pinion B, soarranged as to revolve upon the shaft 0, journaled near the top of themetallic standard D, which is attached to and stands firmly upon thebroad bottom or foot E.

F is a spring dog or pawl designed to control the movement of thegear-wheel A and take the strain of the lift.

G is a handle to the standard D, for the purpose of moving the same morereadily. The standard D is so constructed as to allow the rack-bar H toslide vertically within its sides, and between it and the pinion B, and,being corrugated on the side next to the pinion B, it is readily movedvertically by the meshing with it of the teeth of the pinion. The strapI serves to hold it in place. Its upper end, J, is flattened to sustainany weight which may be placed upon it, while a foot or projection,

k, on its lower end is adapted to lift heavy bodies of any kind. Thegear-wheel A is revolved by my improved lever-socket pinion, whosemechanism is more particularly described in United States LettersPatent, dated August 15, 1882, and numbered 262,819.

It will be seen that my device can be as readily used to raise, to push,and to sustain heavy bodies of any description, Whenever it can beplaced so that they may be made to bear upon the top J or foot K of therack-bar H. Inasmuch as the revolution of the gearwheel A, caused byworking the lever M, the teeth of the pinion B meshing directly withthose of the rack-bar H, forces the latter to rise or fall to the extentdesired, at the same time its movement can be at any moment arrested andsecurely held by means of the dog or pawl F, which controls the movementof the gear-wheel A.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

The combination, in a lifting-jack, of the standard, the toothed bar H,the operatingwheel A, pinion B, dog F, connecting-links, and anoperating-lever, M, having a toothed socket secured to its end andpivoted between the ends of the links, substantially as shown anddescribed. h

In testimony whereof I do affix my signature in presence of twowitnesses.
